The Primary Motor Cortex: The Hub of Motor Learning in Rodents

open access: yesNeuroscience, 2022
The primary motor cortex, a dynamic center for overall motion control and decision making, undergoes significant alterations upon neural stimulation. Over the last few decades, data from numerous studies using rodent models have improved our understanding of the morphological and functional plasticity of the primary motor cortex.

Cellular anatomy of the mouse primary motor cortex [PDF]

open access: yesNature, 2021
Abstract An essential step toward understanding brain function is to establish a structural framework with cellular resolution on which multi-scale datasets spanning molecules, cells, circuits and systems can be integrated and interpreted 1 .

Plasticity and Primary Motor Cortex

Annual Review of Neuroscience, 2000
One fundamental function of primary motor cortex (MI) is to control voluntary movements. Recent evidence suggests that this role emerges from distributed networks rather than discrete representations and that in adult mammals these networks are capable of modification.

Primary motor cortex isolation: complete paralysis with preserved primary motor cortex

Journal of the Neurological Sciences, 1998
We present a left-sided hemiplegic patient with a cerebrovascular lesion involving the medial part of the right frontal and parietal lobes and the corpus callosum, but sparing the hand area of right primary motor cortex (M1). Several studies using transcranial magnetic stimulation demonstrated functional integrity of the efferent pathways from the ...

Primary Motor Cortex Involvement in Alzheimer Disease [PDF]

open access: yesJournal of Neuropathology and Experimental Neurology, 1999
In Alzheimer disease (AD) the involvement of entorhinal cortex, hippocampus, and associative cortical areas is well established. Regarding the involvement of the primary motor cortex the reported data are contradictory. In order to determine whether the primary motor cortex is involved in AD, the brains of 29 autopsy cases were studied, including, 17 ...

Somatotopy in the ipsilateral primary motor cortex

NeuroReport, 2002
Conflicting reports exist about the occurrence, reliability and localization of activation in the ipsilateral primary motor cortex (M1). We re-examined this issue with functional magnetic resonance imaging in 12 volunteers performing right hand, finger, wrist, elbow, foot and tongue movements in two separate sessions.

The human primary motor cortex

Neurology, 1996
Reply from the Authors : We appreciate the insightful comments of Drs. Foundas, Hong, Leonard, and Heilman regarding our recent paper. 1 Our response to each is as follows: We measured the distance between the center of mass of the activated region and the midline for both the finger and elbow movements.
